Typical circuit of 2A lithium-ion charger using LTl769

Relevant key device information applied in this article: LTl769 LTl769 is a current mode pulse width modulation (PWM) battery charging chip produced by Linear Devices Company. It can provide constant charging current and voltage. Due to the usual lithium ion, nickel Hydrogen, nickel-cadmium batteries, etc. all require constant current or voltage for charging, so the charger designed with LTl769 can achieve high-speed charging of lithium-ion, nickel-metal hydride, and nickel-cadmium batteries. 2A lithium-ion charging composed of LTl769 The typical circuit of the converter is as follows
